Check you rear brake switch located near the brake master cylinder. Maybe out

There is an adjustment on the rear brake light switch. First check the wire connection, if good, adjust the switch.

Have you tested the bulbs?

Those rear switches need to be cleaned regularly. I use WD-40 and just work the slider by hand.

That's something that I never thought about. If WD 40 will work, I suppose contact cleaner would work also. Thanks for the tip.

I use WD because it alsolubricates and is not so hard on the rubber boot. It's not a matter of dirty contacts, it is the slider that sticks. Even oil will do the job.

But doesn't WD-40 and oil "attract dirt and dust" more than electrical contact cleaner??

Seems cleaning with WD-40 then a shot of electrical contact cleaner to wash the WD-40 residue away would be a good idea.

Just my thoughts........

May be. It's a pin that rides in plastic. I lube it so it will slide easier. When mine gives me trouble, it either just hangs up sothe pin won't slide to open the contact. Or more often now days, it opens and then won't close so the lights stay on.

The WD-40 was how the dealer fixed it under warranty and I've just been doing it that way ever since.

I had that problem a while back. I completly tore the bike apart looking for the problem thinking it was electrical or worse. Was completly frustrated for about 3 hours just to find out the spring that attaches the foot pedel to the electrical switch was missing.Oh well i guess you live and learn
